THANK YOU FOR PURCHASING ERICA
SYNTHS BLACK SERIES MODULE!
Erica Black Series include high-end, unique
functionality and superior quality modules.
Only the best, highest quality components
are used, all inputs and outputs are
protected against undesired overvoltage.
When designing Black Series, we put design
and usability superior. Big knobs
are assigned to key functions of the module,
which makes Black Series ideal for live
performances. Enjoy!
Erica Synths Black Modulator is modulation
and noise source. It consists of LFO/audio
frequency oscillator with three simultaneous
waveform outputs, Zener diode-based
noise generator with three noise flavours
and clockable S&H circuit.
FEATURES:
LFO with saw, triangle and pulse outputs
LFO/Audio range switch, LFO synchronization
to the external clock
Zener diode-based noise generator for
massive, full spectrum white noise
Pink noise filter
Noise crush knob and crushed noise
output – fade from 1 bit noise to individual
random trigger bursts
Clockable sample and hold circuit.
S&H circuit based on rare, high quality S&H chip
S&H CV and clock inputs
TECHNICAL SPECIFICATIONS:
LFO frequency ............................ 0,2Hz - 25Hz
Audio rate frequency ................18Hz - 750Hz
LFO output level ................................ -5V - +5V
Noise output level ..................................10Vptp
S&H CV input level ......................up to 20Vptp
Power consumption ................48 mA @ +12V,
................................................... 36 mA @ -12V
Module width ............................................10HP
Module depth ........................................25mm
Use this knob to set
LFO and/or S&H clock
frequency.
This knob attenuates S&H
input level. S&H input is
normalled to the white
noise output, so, if nothing
is plugged in CV IN jack,
it will adjust S&H output
amplitude. To get 10Vptp
on S&H output, set the
knob full clockwise.
This is S&H circuit input.
Apply CVs or audio
signals here and turn
them into stepped CVs or
bitcrushed/ringmodulated
audio signals on the S&H
output. S&H frequency
is defined by RATE knob
setting, or incoming clock
frequency, and it can go
into audio range, as well.
These are LFO outputs.
Choose between LFO and
audio rates.
LED gives visual feedback
on LFO frequency.
Use this knob to control
crushed noise flavour –
from 1 bit noise to few
trigger bursts per second.
This is external S&H
clock input. If nothing
is patched here, it’s
normalled to the LFO.
These are noise outputs.
This is S&H output.
Apply an external clock
signal here to synchronize
the LFO frequency!
When in Sync mode,
RATE knob will work as
LFO frequency divider
by 2 and 4, when turned
counterclockwise or
multiplier, when turned
clockwise.
